SASH-FASTENER.

SPECIFICATION forming part of Letters Patent No. 318,998, dated June 2, 1885.

I Application filed February 2, 1584. (No model.)

To aZZ whom it may concern:

Be it known that I, JACOB F. llLiUGANS, a citizen of the United States, and a resident of Bellefontaine, in the county of Logan and State of Ohio, have invented a new and useful Vindow-Sash Holder and Fastener, of which the following is a specification.

My invention is an improvement in windowsash locks and holders, and an improved man ner of protecting the window-sash.

Figure 1 is a plan view of my invention; Fig. 2, a face or front view of my lock; Fig. 3, a plan view of the face-plate, through which lever 0 passes, and also in which the bolt U locks. Fig. at is a top view of the lever, locking-bolt, face-plate, and key.

A is the window-sash; B, the window-jamb; O, the face of the lock; 1), iron rack on the window-sash to protect the sash and engage the locking-dogs; E, screws fastening the rack to the windowsash; F, screws fastening the lock in the jamb; G H, dogs which engage the rack; I l, supplemental dogs; K K, springholding dogs in position. against the rack; L, pin-fastening spring in the lock; M, a pivoted wing, which, by means of key N and lever O, releases the dogs from the rack; P, knob on lever O; Q, pin on which knob P is mounted, and which is attached to bolt U, which, when passed through face-plate R, locks the dogs back from the rack; S, notch or opening in which the bolt is slipped to lock the dogs back; T, larger hole in face-plate through which lever 0 passes; V V, guides on the lever O, in which the bolt U slides; NV X, crown and heel of rack-teeth; Y Z, heels or shoulders of dogs G- H, which engage when the key N is turned to operate the dogs; N N, keys on which the lever 0 may be fitted to operate the dogs; 0 0" O, pivots of wing M and dogs G H.

My object is to provide a lock that practieally looks at any point desired, the arrangement being such that my device will lock with every change of each and every three thirtyseconds of an inch in the position of the sash, and also to provide one easy and convenient to operate, durable, burglar-proof, one that does not wear either sash or frame, will apply to windows with or without weight, looks as securely from raising as from lowering, will apply to all manner of windows either with or without false jalnbs, is self-locking, needs no extra movement of the hand to lock the sash, prevents the window from rattling, will hold the sash level, not allowing it to sag on opposite side of the window, and does not extend through the jainb to interfere with the weight passing up or down.

One of the objects in using the supplemental dogs is that the rack-teeth can be made large enough to give a large bearing and the dogs look at short distance at same time. In the drawings it will be seen that the dogs will lock at'half the distance of the length of atooth on the rack, and the dogs will lock the sash securely whether the sash fits loosely or tight in the frame, and it will look just as securely even though the sash or frame should contract or expand after the lock is put on.

By using the supplemental dogs all probability of the locks not catching or slipping is avoided, for should the dog G or H catch near the point of a tooth and slip over it the supplemental dogs are in position to take full hold at once.

The operation and construction of my device are as follows: The iron rack Dis attached to the window-sash by screws. This rack prevents any wear on the window-sash,and is provided with teeth three-sixteenths of an inch in length, which engage the dogs of the lock. The lock is set into thejamb of the frame, and consists, essentially, of the dogs G H and supplemental dogs I I and spring K. The dogs G Hare pivoted at O O, and a shoulder, Y, on the dog H abuts against a shoulder, Z, on the dog G. In the pivot of the dog H is-a square l;ey-hole,in which the keyN fits. On the end of this key is attached a lever, 0, having button 1?, on the end by which the key N can be turned and the dog H disengaged from the rack. hen the dog H is turned on its pivot-,the shoulder Y engages the shoulder Z and disengages the dog G from the rack at the same time. The releasing of the dogs G H releases the supplemental dogs I I also. As soon as the knobP is released the spring K causes the dogs to en-.

gage the rack again. The supplemental dogs I l have rounded or ball-like ends, which fit and turn closely in circular openings in the dogs G H. The other ends of the dogs I I are of shape to iit the teeth of the rack, and are of ICO length to reach one and one-half tooth past the respective dogs G H, so that when one of the dogs and one of the supplemental dogs are engaged with the rack, as shown in the drawings, the other two are ready to engage when the rack has moved half the distance from IV to X, or half the length of a tooth. Thus I prefer to make the teeth of the rack three-sixteenths of an inch long, and it will be readily seen that by the arrangement of the dogs the window can be locked at each change of the three thirty-seconds of an inch in the position of the window-sash. XVhere the windows have weights, or for other reasons it is not convenient to insert the key N in the pivot O, I insert it through the pivot O and operate the dogs by means of the wing M. Vhen the key is inserted through the pivot O, the wingM is not used. When the lever O is depressed by button I? to release the dogs, and it is desiredto hold them back out of contact with the rack, the button is slid forward on its pin Q in the slot P, which slides the bolt U until its front end passes through the hole S in the face-plate and locks the lever O in position and prevents the dogs from springing back into contact with the rack; but a backward pull of button I? will release the bolt U from hole S in the face-plate and allow the dogs to engage the rack again.

' XVhat I claim is- 1. In a window-sash fastener and holder, the combination, with dogs G H, having the shoulders Y Z and rack I), of the leVerO and bolt U, for operating and locking the dogs.

2. In a window-sash holder and fastener, the combination, with; the dogs G H, having the shoulders Y Z and rack D, of the supplemental dogs I I, as and for the purpose set forth.

3. The eo1nbination,with dogs G H, having the shoulders Y Z and rack D, of the lever O and wing M, in a windowsash holder and fastener, as. and for the purpose set forth.
